IPC: H04Q1/45
Filed: 1992-02-10
Abstract: PURPOSE:To improve the noise resistance and voice interrupting performance of a system by using a DTMF receiver equipped with a DTMF signal discrimination circuit. CONSTITUTION:Three signal power calculating means calculate the powers of signals in an entire band, high group signals in a DTMF band, and low group signals in the DTMF band from an input signal.

Title: Preprocessing method for compound semiconductor substrate
Inventor: SATO JUNICHI
IPC: H01L21/31
Filed: 1993-02-12
Abstract: PURPOSE:To constitute an MIS-type device that exhibits good characteristics an a compound semiconductor substrate.

Abstract: PURPOSE:To obtain good responsiveness extending over both high and low areas of luminance, by executing the focusing by use of a filter output of a variable characteristic when luminance of an object to be photographed is high, and the latest control information when it is low. CONSTITUTION:When luminance of an object to be photographed is high, a comparator 12 outputs L, the first selecting circuit 13 selects a strobe pulse phiS as a reset pulse phiR, and the second selecting circuit 14 selects a filter output P1.

When luminance of the object to be photographed is low, such operations of 1 period as charge accumulation, control information calculation, etc. are executed when the lens 16 is stopped, control information outputted in the end of the period is read by the driving circuit 15 in response to generation of the strobe pulse phiS, and in accordance with its control information, the lens 16 is moved. By constituting in this way, it is possible to obtain the good responding characteristic extending over both high and low areas of luminance.

Abstract: PURPOSE: To realize the high-speed sending for several tone signals by accelerating the fall of the digital filter output with the clear pulse applied to the switching transistor.  
     CONSTITUTION: High-gain amplifier 9 is connected between input terminal 1 and output terminal 10, and capacitors 3∼6 are branched in parallel out of amplifier 9. In addition, switching transistors Tr11∼14 which have the sequential switching via clock pulses 19∼22 featuring the cycle of the desired reception frequency are connected to capacitors 3∼6. Thus capacitors 3∼6 receive the sequential charge and discharge to be made pass through the desired frequency, delivering the digital signal to terminal 10. Then clear pulse 28 is applied to the bases of Trs11∼14 of such constitution as mentioned above as soon as the reception frequency is switched. Thus all of Trs11∼14 are turned on while clear pulse 28 is being sent out to flow the charge/discharge current to each of capacitors 3∼6. And the signal earthed with the low impedance, and the signal to be transmitted to amplifier 9 is turned into waveform 29. Then the sudden fall is secured for waveform 29, thus ensuring the high-speed sending for several tone signals.

Title: Truck with lift device
Inventor: WADA NORIYUKI
IPC: B62B3/06
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the trouble where the lift table of a truck is inoperable, due to a change in the width of a carried article, and a quick inserting work cannot be done, due to the lateral dislocation of the lift table, at the time of advancing the truck via an eye measurement and inserting the lift table in space under the carried article. SOLUTION: A lift body 30 is lowered for a body 11, prior to the handling of a container 1, and both engagement bodies 35 are oscillated inside. In this case, an oscillation limit for the inner inclination posture of the engagement bodies 35 is taken at a position for contact with an oscillation restriction body 30, thereby maintaining the constant position of the engagement bodies 35. Also, the container 1, when dislocated laterally at the time of being positioned between the engagement bodies 35, is guided with the corner of a handle part 4 in contact with the handle guide surface 38B of the restriction body 38. Furthermore, a truck 10 with a lift device and the container 1 are relatively dislocated laterally, thereby avoiding the collision of the oscillation restriction body 38 with the container 1.  Also, when the lateral breadth of the container 1 is large, the engagement restriction bodies 35 automatically oscillate to have a standing posture and support the engaged part 3 of the container 1.

Abstract: PURPOSE:To eliminate fluctuations in the oscillation frequency with a rise in the temperature during operating time by forming the core of a strap ring with ceramic and by covering its internal and external surfaces with mutually insulated conductive films and connecting it to vanes alternately through conductive films. CONSTITUTION:The core of a strap ring 5 is formed with ceramic whose internal and external surfaces are each covered with mutually insulated conductive films, and is alternately connected to a vane 2 through a connection point 6a to the external surface and another connection point 7a to the internal surface.
